VALVE.

Specification of Letters Patent.

Patented Apr. 18, 1916.

Application filed August 29, 1914. Serial No. 859,186.

To all whom it may concern: Be it known that I, FREE HUBBARD, a c1t1- zen of the United States, residing at Globe,

in the county of Gila and State of Arizona, have invented new and useful Improvements in Valves, of which the following is a specification.

This invention relates to valves and particularly to check valves used in connection with cylinder pumps.

The principal object of the invention is to provide a valve which may be conveniently attached to the ordinary pump cylinder and which will have a capacity equal to the capacity of the discharge pipe with which it is associated.

Further objects of the invention will appear as the following description is read in connection with the accompanying drawing, which froms a part of this application, and in which Figure 1 is a vertical sectional view. Fig. 2 is a bottom plan view.

Referring more particularly to the drawing, 1 represents a casing provided at its upper end with an internally threaded nipple 2 into which the discharge pipe 3 is screwed. The lower end of the casing is ground ofi' and secured thereon by means of lag screws 4; is a combined disk seat and spider 5 having a stem guiding yoke 6 formed integral therewith and adapted to receive the lower end of the valve stem 7 the upper end being fitted within a collar 8 flopiea of this patent may be carried by the cross piece 9 which is, as shown, an integral part of the casing 1. The valve stem is reduced intermediate its length and secured upon the same is an ordinary disk valve 10 having its outer edge or periphery beveled, as shown at 11, to engage the beveled seat 12 on the member 5. As shown, the valve disk 10 is of equal diameter with the internal diameter of the discharge pipe so that no restriction is oiiered to the flowing liquid.

What is claimed is In a valve, a casing, an apertured bridge extending across the casing and integral therewith, a discharge pipe threaded into the casing, a valve seat ring secured to the lower end of the casing and detachable therefrom, an apertured bridge ring integral with and extending across said ring, a valve rod slidably mounted in the bridge pieces, and having its lower portion reduced to define a shoulder, a nut mounted on the said reduced portion and disposed above said bridge ring, and a valve disk carried by the reduced portion of the rod and lying between said nut and said shoulder and adapted to fit the seat on the ring.

In testimony whereof I affix my signature in presence of two witnesses.
